Detailed and direct analysis of semen, including sperm morphology, enables a diagnosis of male fertility. This study aimed to describe an economical and verified protocol for canine spermiograms and compare the effectiveness of Sperm Stain and Sperm Blue (Microptic, Spain) in veterinary practice. Sperm assessment was conducted manually, using a standard optical microscope, and via computerized semen analysis using the SCA CASA (Sperm Class Analyzer CASA System-MICROPTIC, Spain). This study showed that Sperm Blue is a better solution for computerized sperm quality analysis of healthy dogs. At the same time, Sperm Stain turned out to be more helpful in identifying specific morphological defects of sperm. Automated canine sperm morphology analysis worked better with Sperm Blue stain, but Sperm Stain simplified manual evaluation of various organelles' defects. Standard, manual examination is more error-prone for an inexperienced andrology technician, but it seems to be still a gold standard technique for canine sperm assessment.

Ethylene glycol (EG) has been employed as a cryoprotectant for many years in mammalian semen cryopreservation but not assessed for birds except for its recently illustrated beneficial effects on commercial chicken lines. The Indian red jungle fowl is facing trouble in its native range due to human encroachment. Therefore, the present study was designed to elucidate the cryoprotective effect of different EG concentrations (5%, 10%, 15%, and 20%) on frozen Indian red jungle fowl semen.

Background: Klinefelter syndrome (KS) is an uncommonly recognised condition typified by gynaecomastia, small testes and aspermatogenesis. It is caused by a supernumerary X chromosome, resulting in a 47 XXY karyotype. Since its first description, the phenotype of KS has evolved and there is a much greater appreciation of the subtle features of the condition.

Magnetic microrobots are significant platforms for targeted drug delivery, among which sperm-inspired types have attracted much attention due to their flexible undulation. However, mass production of sperm-like soft magnetic microrobots with high-speed propulsion is still challenging due to the need of more reasonable structure design and facile fabrication. Herein, a novel strategy is proposed for large-scale preparation of microalgae-based soft microrobots with a fully magnetic head-to-tail structure, called AlgaeSperm with robust propulsion and chemo-photothermal performance.

Background: Direct-to-consumer (DTC) semen analysis (SA) products obviate barriers that deter men from clinic testing and have made strides in providing higher quality data. However, it is unclear how well these products adhere to the 2021 WHO guidelines on examination and processing of human spermatozoa as they pertain to the evaluation of male fertility.
Objective: We investigate the content and adherence to clinical guidelines associated with consumer-facing information on DTC analysis products.

Background: Varicocele is associated with a progressive decrease in male fertile potential, but it has yet to be determined if the duration of varicocele is associated with altered sperm functional quality.
Objectives: This experimental study investigated the time-dependent effects of varicocele on spermatogenesis, sperm parameters, and sperm functional traits.
Materials And Methods: Thirty-five mature male Wistar rats (200 ± 25 g) were included.
